TVB-3664は、ヒトおよびマウスの脂肪酸合成酵素(FASN)に対するIC50値がそれぞれ18 nMおよび12 nMの経口活性を持つFASN阻害剤である。TVB-3664はTVB-3166のアナログであり、乳癌、前立腺癌、大腸癌、および肺癌の前臨床研究において抗腫瘍活性を示している。さらに、TVB-3664はSARS-CoV-2ウイルスを強力に抑制し、そのEC50値は0.07 nMであり、レムデシビル(EC50 = 0.4 nM)よりも5倍強力である。
In vitroでは、A549肺癌細胞をTVB-3664(50 nM)で72時間処理した結果、パルミトイル-α-チューブリンの67%およびパルミトイル-β-チューブリンの92%が失われた。複数の大腸癌(CRC)細胞株をTVB-3664(200 nM)で処理した結果、細胞の脂肪酸およびリン脂質の含有量が大幅に減少し、AktおよびErk1/2経路の活性を低下させることで腫瘍細胞の増殖と生存が抑制された。
In vivoでは、大腸癌を持つマウスにTVB-3664(6 mg/kg)を4週間経口投与したところ、腫瘍細胞内のスフィンゴシンキナーゼ2(SPHK2)の発現が減少し、焦点接着マーカーであるp-FAKおよびp-パキシリンタンパク質が活性化された。脂肪肝疾患を持つマウスにTVB-3664(0.3-10 mg/kg)を8週間経口投与したところ、肝臓の組織学的重症度スコアおよび炎症性サイトカインIL-1βのレベルが用量依存的に減少した。
